It will be Hultzen’s second start with the Triple-A Rainiers after being called up last week from Double-A Jackson. In his debut Saturday in Colorado Springs, he lasted just three innings and gave up five runs on five hits, striking out three but also walking five.

Moyer, meanwhile, is making his debut with the Toronto Blue Jays organization, which just signed him to a minor-league contract after he was released — at his request — by the Baltimore Orioles. Moyer, 49, became the oldest pitcher to record an MLB win earlier this season when he was with the Colorado Rockies. He signed with the Orioles after the Rockies designated him for assignment.

Thursday’s matchup is exciting for its novelty. Many Mariners fans, desperate for better pitching in the big leagues, are anxious to see Hultzen do well with Tacoma. And Moyer, who spent 11 of his 25 MLB years with the Mariners, is a beloved figure in the Seattle area, not just for his pitching but for his philanthropy.
